Elmar f=9cm 1:4 Handling and Mechanics

The lens is compact, especially unusual to see such a small diameter lenses and frames. As soon as it took in hand, immediately it appreciated the constructive and good ergonomics, and it became clear why so many photographers have fanatic love of the Leica brand. The designers did a good job on the design, I too can say, fell in love with this design.

The lens is assembled in a metal frame gray-silver color. Lens length 86mm. A diameter of the filter is 33mm. Here such interesting proportions.

In the middle of the barrel is the focusing ring. It is made of metal, not rubberized and has solid small incisions in order to make it convenient to rotate it. It is rotated by 270 degrees.

By rotating the ring, the lens is extended by 12mm. It is a pity that I could not use it housing on Nikon reflex camera.

On the barrel applied focusing scale in meters, and the depth of field tags at different apertures.

Below, near the bayonet is 10mm black decorative ring. It is because of this ring, this version received by collectors the name «Black Belt».

The diaphragm closes smoothly and has 15 blades it is not blackened.

The front element is covered with a metal cap, which flaunts embossed Leica logo.

The lens is composed of two parts. The front part is optical, elements in barrel, and the back part is mechanical, focusing helicoid.

Front part easily unscrewed from the helicoid, and thus it can be installed on another helicoid to get the focus to infinity in the SLR cameras. This look at it below.

 

Mount Elmar f=9cm 1:4 on DSLR Camera

Despite the fact that the lens for rangefinder camera, because it has retrofocus optical design with a long flange distance, as well as due to the fact that front optical part easily unscrews, you can mount it on any SLR camera using the shorter helicoid, which would compensate flange distance.

I used homemade focusing helicoid based on Industar-50 3.5/50.

But there are difficulties. Despite the fact that mounting front part to helicoid threaded connection, it is a nonstandard thread M33x0,75. So I could not do without the help of the turner.

Familiar turner machined me this is a transitional step down ring M42-M33, I screw it in my focuser.

Do not forget to blacken the inside of the ring, to eliminate possible parasitic flare. By the way, the native helicoid has an excellent blackening inside.

To compensate for the flange distance, I needed to add a small extension tube, and M39-M42 adapter  (4 mm thick, without the 4 mm segment offset and nonperfect though infinity will focus range is uncomfortable). And finally, for installation on a Nikon camera must also M42-Nikon adapter.

That's how the lens looks to the new helicoid, not bad.

Elmar f=9cm 1:4 Character and Bokeh

The lens has a Tessar optical design. Therefore, the character is quite predictable. But unlike the Zeiss Tessar's and Soviet Industar's Elmar character seemed me more interesting, more ductile.

As for the backlight, it does not copes. It should be strong direct light to get into the frame, and you get the picture overcast veil.
I recommend using the hood.

In general, photographing at Elmar, avoid strong direct and lateral light and be all right.
